Description
Technical field:
The present invention relates to the device that the sump oil that produces in the field joint stations extraction liquid treatment facility is recycled.
Background technology:
In recent years, black solid particulate sump oil has appearred containing in succession in the extraction liquid treatment facility of many oil fields part joint station, wherein at the sewage slurry tank with remove the sump oil on oil tank top, because a large amount of black solid particulate enrichment, caused very big difficulty for extraction liquid and oily water treatment, not only make the water quality deterioration of handling the back oily(waste)water, and can cause the pollution of oil-containing sewage filter and produced-water reinjection system when serious; If the sewage slurry tank and the black solid particulate sump oil that contains that removes the enrichment of oil tank top are recovered to when handling in the dehydrating of crude oil system, excessive layer in the middle of in electrical dehydrator, forming easily, often cause electrical dehydrator to stride electric field, seriously influenced the ordinary production operation of dehydrating of crude oil system.Be normally carrying out of extraction liquid and oily water treatment in the guarantee joint station system, at the sewage slurry tank with remove the sump oil of enrichment in the oil tank and often have to adopt the mode that it is directly effluxed when too much, so not only lose a large amount of crude oil, also caused the serious environmental pollution.This in recent years sump oil recycling problem begins to extend in the joint station in many oil fields, and is the trend that increases the weight of year by year, seriously injures normally carrying out of extraction liquid and oily water treatment production.Therefore, sulfur compound sump oil in the joint station is recycled and controls become in the field produces an important difficult problem anxious to be solved.
Summary of the invention:
The objective of the invention is to contain black colloidal state Iron sulfuret particle sump oil, developed out black colloidal state Iron sulfuret particulate treatment unit in the removing sump oil that is suitable at what formed in the joint station extraction liquid treatment facility.It comprises that sump oil list screw rod lift pump 1, line mixer 2, three-phase separating centrifuge 3, sewage withdrawing can 4, sewage reclaim pump 5, heating surge separator 6, sump oil lift pump 7, solid sediment withdrawing can 9, sediment purge tank 10 and lift pump 11, their mode of connection is: an end of line mixer 2 links to each other with an end of single screw rod lift pump 1, the other end of line mixer 2 links to each other with the inlet of separating centrifuge 3, also is connected with chemicals dosing plant 15 on the line mixer 2; The sewage outlet of separating centrifuge 3 links to each other with an end of sewage withdrawing can 4, and the other end of sewage withdrawing can 4 links to each other with the end that sewage reclaims pump 5, and the other end that sewage reclaims pump 5 connects Sewage treatment systems; The separation slag outlet of separating centrifuge 3 links to each other with an end of solid sediment withdrawing can 9, and the other end of solid sediment withdrawing can 9 links to each other with an end of sediment purge tank 10, and the other end of sediment purge tank 10 links to each other with an end of lift pump 11; The other end of lift pump 11 links to each other with the inlet of separating centrifuge 3, and the liquid in the sediment purge tank 10 promotes through lift pump 11 and enters separating centrifuge 3, outside the sediment drain tank in the sediment purge tank 10; The crude exports of separating centrifuge 3 link to each other with the inlet of heating surge separator 6, the outlet of heating surge separator 6 links to each other with the suction port of sump oil lift pump 7, the other end of sump oil lift pump 7 links to each other with going to the dehydrating of crude oil system by pipeline, below sump oil lift pump 7 and the pipeline that goes to the dehydrating of crude oil system to link to each other branch line being set links to each other with an end of sediment purge tank 10, after sump oil separates in heating surge separator 6, be positioned at the isolated oil of heating surge separator 6 internal upper parts and enter and the pipeline that goes to the dehydrating of crude oil system to link to each other, enter into dehydrating of crude oil system or directly outer defeated by sump oil lift pump 7; Be positioned at the sump oil isolated sewage in below and a small amount of sediment in the heating surge separator, enter sediment purge tank 10 by pipeline and branch line.The present invention is according to the problem that the sump oil recycling that produces in the field joint stations extraction liquid treatment facility is existed; the portable sump oil reclaiming clean treatment unit of developing out; can effectively the black colloidal state Iron sulfuret particle sump oil that contains that produces in the field joint stations extraction liquid treating system facility be purified; black colloidal state Iron sulfuret particle in the sump oil is thoroughly separated from sump oil; avoided the enrichment of the black colloidal state Iron sulfuret particle sump oil that formed in the extraction liquid treating system facility; and be recovered to electro-dewatering and carry out processed and cause the electrical dehydrator electric field that collapses; and then influence the problem of normal production run; the present invention both can be purified the black colloidal state Iron sulfuret particle sump oil that contains that produces in the joint station extraction liquid treatment facility to handle and reclaim; avoided in order to guarantee normal production a large amount of crude oil effluxed environmental pollution and the waste that is caused again; thereby improved the processing efficiency of whole joint station production technique; protected environment; guaranteed the smooth running of dehydrating of crude oil system; improved the dehydration quality of crude oil; and improved re-injection water water quality; make the oily(waste)water re-injection up to standard after the processing and reduced environmental pollution; and guaranteed whole recovery of sump oil and sewage, therefore created good economic benefit and social benefit.In addition because this cover treatment unit system support equipment that is small-sized sled shapeization, it is easy to have a treatment process, and treatment effect is good, flexible operation, and characteristics such as convenient transportation are advanced person's treatment unit comparatively at present, can the extensively supporting oil field development system that is used for.
